Assessment Instruments: One week prior to treatment, subjects will be administered a battery of clinical rating scales and questionnaires to determine the severity of their BDD and any secondary symptoms. This same assessment battery will be given immediately following treatment to determine the level of efficacy of each of the two treatment groups. These scales include the Yale-Brown Obsessive-Compulsive Scale Modified for BDD (BDD-YBOCS), Body Dysmorphic Disorder Examination-Self Report (BDDE-SR), BDD Diagnostic Module (BDDDM), Y-BOCS Symptom Checklist, Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), Hamilton Rating Scale for Depression (Ham-D), Hamilton Anxiety Rating Scale (HARS), Fixity of Beliefs Questionnaire, Global Assessment of Functioning (GAF), NIMH Global Obsessive-compulsive Scale, Brown Assessment of Beliefs Scale (BABS), Obsessive-Compulsive Inventory (OCI), Obsessive-Compulsive Rating Scale (OCON), Fear Survey Schedule (FSS), and the Revised Willoughby Questionnaire. These will take approximately 90-120 minutes to complete.
